Wind energy is one of the earliest energy sources used by human beings.The utilization of wind energy in modern society is mainly realized by wind power generation.Blade design technology is the core design technology of wind turbines.At the same time,the wake effect caused by wind turbines working becomes an important factor affecting the overall output power of wind farms.Therefore,it is of great significance to study the aerodynamic characteristics of wind turbine bladesThis paper takes 2MW horizontal axis wind turbine as the research object,and its main contents are as follows:(1)Based on Wilson optimization algorithm,the parameters of megawatt wind turbine blades are optimized,and a new blade modeling method is used to complete the aerodynamic shape and structure design of wind turbine blades combined with SolidWorks software.Firstly,based on Wilson algorithm,the blade optimization model is established in MATLAB to obtain the data of installation angle and chord length of blade elements in each section,and then the results are fitted and corrected to complete the optimization design of blade airfoil parameters;secondly,using SolidWorks surface modeling function and Profili software,the spline curve of blade section is drawn in SolidWorks,and finally the blade and the whole machine three are completed.The construction of dimension model.(2)Based on Wilson optimization algorithm,the parameters of megawatt wind turbine blades are optimized,and a new blade modeling method is used to complete the aerodynamic shape and structure design of wind turbine blades combined with SolidWorks software.Firstly,based on Wilson algorithm,the blade optimization model is established in MATLAB to obtain the data of installation angle and chord length of blade elements in each section,and then the results are fitted and corrected to complete the optimization design of blade airfoil parameters;secondly,using SolidWorks surface modeling function and Profili software,the spline curve of blade section is drawn in SolidWorks,and finally the blade and the whole machine three are completed.The construction of dimension model.The work in this paper can provide a reference for the optimization design of megawatt wind turbine blade shape and wake information analysis.The results obtained have important practical significance for the design and development of wind turbine blades and wind turbine layout research.
